hi. im new in using rowguid, i want to know how long can this datatype can hold. and is there a chance that value can be duplicate or the sql is checking it already before it create a new one.
and what will happen if i select yes in isrowguid. thnx
Dear Folks, can you please tell me, how many newid's can be generated by an sql server instance? and the newid generated by one instance can possibly be generated by another instance ? please give me brief regarding this
Is there a limitation of using:set @sessionID = NEWID()would there be a simular NEWID() being generated if used in a databaseapplication.Eugene Anthony*** Sent via Developersdex http://www.developersdex.com ***
I have the following to create a table in sql server...... CREATE TABLE [dbo].[myTable] ( Id VARCHAR(50) NOT NULL, fldDate SMALLDATETIME, guid uniqueidentifier NOT NULL PRIMARY KEY
) GO I can't seem to find the right syntax to make the uniqueidentifier a rowguid. Thanks, Zath
I recently been assigned to a project that has an ms-access front end and sql server 2000 sp4 as the database engine. The database was replicated (merge replication) but for some reason they drop replication and when they tried to put it back on they got allot of problems and so they paused it. My task now is to make it work again. After allot of reading I desided to clean the database and start from the beginning. Using some scripts and instructions on a copy of the database I cleaned all the tables related to merge replication but when I went back to ms-access to update a record I got an error "invalid column name 'rowguid'" . I checked all my tables in my database but I find not such column as it was dropped using the scripts. Any ideas that I can use?
hi,I have a database that has Primary Key constraints on every table. Yetwhen I run the replication wizard and try to configure mergereplication the wizard notifies me that it will create a rowguid onthe tables even though they already have a primary key.anybody know how to avoid the rowguid column from being created?regards,Doron
I'm new to replication and database management so I will like some understanding and guiding as this is a new task for me.
I was given a copy of a database with merge replication on it and doing allot of reading and using some scripts I cleaned replication (or so Im thinking) and tryed to use it again on the ms-access front end. When I try to update some data I get "invalid column name 'rowguid'" , but no such column exist in my database as it was dropped.
I'm trying to set up a merge publication in MSSQL 2005 SP1.
I have a database which I have successfully made into a merge publication. When I run the snapshot agent, several articles are processed successfully, then I encounter an error with the following: Invalid column name 'rowguid'
Note that none of the tables contain 'rowguid' columns before this process - I let MSSQL automatically create these as needed.
The replication monitor details the following error:

I've a table with one column specified as rowguid. An insert into this table is done in a stored procedure, which should return the new rowguid by an output parameter. How can I obtain the autoassigned rowguid of the inserted record? is there something like ident_current which is used for identity-columns?
when you use newid() is that a new uniqueidentifier for the database or for the table???I have a changelog that captures newly created users first and gives them a newid, then i want to approve that change and copy the newid generated for that user into the user table. Will I run into duplicate id's that way???
Excuse my ignorance because I don't do advance db related programming,but have no other choice at the moment. My experience is limited tosimple queries.I need to have the following query display the recordset in random orderbased on RecordID (unique key) if possible. I tried the ORDER BY NewID()at the end and it generated an error (ORDER BY items must appear in theselect list if SELECT DISTINCT is specified.) I guess because of the subquery. I would also like for the recordset to display a different 10records on each hit to the page, not just the same 10 records in randomorder. I wasn't sure if the SELECT commands I have in place aresufficient for this task.Thanks in advance for any assistance.SELECT DISTINCTTOP 10 dbo.ShowcaseRides.RecordID,dbo.ShowcaseRides.CustomerID, dbo.ShowcaseRides.PhotoLibID,dbo.ShowcaseRides.Year,dbo.ShowcaseRides.MakeShowcase,dbo.ShowcaseRides.ModelShowcase, dbo.ShowcaseRides.VehicleTitle,dbo.ShowcaseRides.NickName,dbo.ShowcaseRides.SiteURL,dbo.ShowcaseRides.ShowcaseRating, dbo.ShowcaseRides.ShowcaseRatingImage,dbo.ShowcaseRides.ReviewDate,dbo.ShowcaseRides.Home,dbo.ShowcaseRides.EntryDate, dbo.Customers.UserName,dbo.Customers.ShipCity, dbo.Customers.ShipRegion,dbo.Customers.ShipPostalCode,dbo.Customers.ShipCountry, dbo.Customers.LastName,dbo.Customers.FirstName, dbo.Customers.MemberSince,dbo.ShowcaseRides.Live,dbo.ShowcaseRides.MemberLive, dbo.Accessories.Make,dbo.Accessories.Model, Photos.PathFROM dbo.ShowcaseRides INNER JOINdbo.Customers ON dbo.ShowcaseRides.CustomerID =dbo.Customers.CustomerID INNER JOINdbo.Accessories ON dbo.ShowcaseRides.MakeShowcase= dbo.Accessories.MakeShowcase ANDdbo.ShowcaseRides.ModelShowcase =dbo.Accessories.ModelShowcase INNER JOIN(SELECT MIN(dbo.ShowcasePhotos.PhotoPath)AS Path, RecordIDFROM dbo.ShowcasePhotosGROUP BY RecordID) Photos ONdbo.ShowcaseRides.RecordID = Photos.RecordID INNER JOINdbo.ShowcasePhotos ON Photos.Path =dbo.ShowcasePhotos.PhotoPathWHERE (dbo.ShowcaseRides.MemberLive = 1) AND (dbo.ShowcaseRides.Live= 1) AND (dbo.ShowcaseRides.MakeShowcase = @MMColParam)ORDER BY dbo.ShowcaseRides.EntryDate DESCRegards,Darin L.

Why am I getting a different numbers of distinct ids in those queries?
USE AdventureWorks go Declare @myXml as xml set @myXml = ' <lol>omg</lol> <lol>rofl</lol> ';
select locations.*, T.c.value('.','nvarchar(max)') from ( select newid() as Id from Production.ProductModel where ProductModelID in (7, 8) ) as locations cross apply @myXml.nodes('(/lol)') T(c);
select mytable.* , T.c.value('.','nvarchar(max)') from ( select newid() as Id union select newid() ) as mytable cross apply @myXml.nodes('(/lol)') T(c);
I've been trying to figure out why these two return a different amount of distinct ids... Is that a bug in optimization?

I have a view which at the moment has no unique identifier on each record. When I try adding a column definition to the view such as NEWID() as TransactionId, the view then cannot 1) be selected into a temporary table, or 2) queried on other columns in the table. In either case I end up with an empty result set.
I believe I have a way around this for my purpose, which was principally testability. However, can anyone enlighten me as to how and why this happens?
I am looking to preserve the ROWGUID column that is created automatically when a table is added to a publication as I have noticed that the column is removed and readded (with new values) each time the publication is deleted and recreated. We are planning on using the values in the rowguid column for a non-replication purpose, and don't wish the column to be removed or the values to be reset in the event the 'owning' publication is dropped for whatever reason. I've done some research and have identified the preserve_rowguidcol column of the sysmergearticles table as a candidate for achieving the desired goal. Before moving forward, I wanted to ask for input regarding this. Are there any best practices I've overlooked on this topic? Neither Google nor this forum's search results yield any real discussion on this topic.
I have an application being developed using SQL server. The data is captured at various remote areas and the SQL servers are not physically connected to each other.
Periodically either through a replication / backup process i plan to update the data from various servers into a central database.
Can i use the NewID() function to generate a unique ID which i can use as a primary key that would not be duplicated across all these servers?
if not Please suggest a solution to maintain the uniqueness of the transaction.
I have 2 tables, Artists and Artworks. I have a query:
SELECT TOP (4) dbo.Artists.ArtistID, dbo.Artists.FirstName + ' ' + dbo.Artists.LastName AS FullName, dbo.Artworks.ArtworkName, dbo.Artworks.Image FROM dbo.Artists INNER JOIN dbo.Artworks ON dbo.Artists.ArtistID = dbo.Artworks.ArtistID ORDER BY NEWID()
This query returns random images, but the artists are sometimes repeated. I would like to have DISTINCT Random Artists returned, each with a random image. I tried various subqueries, but I just get error messages. Any help would be appreciated. Thnks,
Is it possible to use NEWID() as a parameter to a stored procedure inSQL Server 2000. I keep getting a "Line 1: Incorrect syntax near ')'"error.ALTER PROCEDURE dbo.StoredProcedure1(@x uniqueidentifier)AS/* SET NOCOUNT ON */RETURNStoredProcedure1 NEWID()go"Line 1: Incorrect syntax near ')'"Thanks in advance
Hello.So the scenario is a little complicated.I am joining two tables.Table 1 is derived; it has one row; it has a column based from newid()Table 2 joins to table 1 and reuses the newid() value from table 1 in table 2's rowsBecause there is only one row in Table 1, the value of newid() REPEATS in Table 2The bug is that the NewId() value from Table1 is REGENERATED with every Table 2 record.I created a blog about this because it takes a code sample to demonstrate:http://jerrytech.blogspot.com/2008/04/sql-2005-tsql-bug-with-newid-in-derived.html
After I setup the merge replication in SQL SERVER 7.0, there is a rowguid column (datatype uniqueidentifier) inserted into each table in the both the source and destination database.
I need to get rid of the rowguid column in all tables. I deleted the replication, but the column still existed.
Is there an easy way to get rid of all the rowguid column in the database? Thanks for your reponse in advanced.
Hi There, I'm having a problem retreiving the auto generated Guid after inserting anew record with NEWID(), my stored proc is as follows:SET @uiTransactionID = NEWID() INSERT INTO Transactions (uiTransactionID) VALUES (@uiTransactionID) IF @@ERROR = 0 AND @@ROWCOUNT = 1 BEGIN SELECT @uiTransactionID AS '@@GUID' RETURN 0 END And the return on my insert statement is: command.ExecuteNonQuery();m_uiTransactionID = (Guid)command.Parameters["RETURN_VALUE"].Value; I can never retreive the newly generated Guid, can onyone spot where i'm going wrong? Many thanks Ben
Hi,What I am trying to do is to get the new ID for every record is inserted into a table. I have a For...Each statement that does the loop and using the sqldatasource to so the insert. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ myConnectionString%>"> <InsertParameters> <asp:Parameter Name="NewID" Type="int16" Direction="output" /> </InsertParameters> </asp:SqlDataSource> Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim sqlSelect As String Session("Waste_Profile_Num") = 2 Session("Waste_Profile_Num2") = 5
sqlSelect = "SELECT Range, Concentration, Component_ID FROM Component_Profile WHERE (Waste_Profile_Num = " & Session("Waste_Profile_Num").ToString() & ")" SqlDataSource1.SelectCommand = sqlSelect
Dim dv As Data.DataView = CType(SqlDataSource1.Select(DataSourceSelectArguments.Empty), Data.DataView) For Each dr As Data.DataRow In dv.Table.Rows
Protected Sub SqlDataSource1_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Inserted Session("NewID") = e.Command.Parameters("@NewID").Value.ToString
End Sub What I have done so far is to display the new id and I am going to use that return id later. However, the first time through the loop, I am able to get the new id but not the second time. So, I wonder, how do I every single new id each time the INSERT statement is executed?STAN
I'm migrating a web based system to SQL server. I'm planning on using the SQL server function NewID() to create unique keys for many of my records in many different tables. I'm just wondering if NewID() is guaranteed to return a value that does not already exist in my database. I mean obviously once you have a certain number of records (a hell of a lot) you'd be breaking the odds to never come up with a duplicate. Do I need to make sure the result of NEWID() doesn't already exist?Thanks
I currently have a table called stores. I've just added a uniqueidentifier column called store_guid to the stores table. The table currently has about 500 records in it and now i'm trying to set each store_guid = to a newid(). I've tried using UPDATE stores SET store_guid = newid() . however, that doesn't work because i think it's trying to set each record equal to the same guid using that approach. All i need to do is fill in my new column with new guids. any ideas?
I'm trying to use the NEWID function in dynamic SQL and get an errormessage Incorrect syntax near the keyword 'ORDER'.

I have setup merge replication which successfully synchronizes with a group of desktop users using SQL Compact Edition.
However now I have setup Article Filters and when I attempt to regenerate the snapshot I get the following error:
Invalid column name 'rowguid'.
Failed to generate merge replication stored procedures for article 'AssignedCriteria'.
When I look at publication properties at the Articles page.. All my tables have the rowguid uniqueidentifier successfully added to tables and selected as a compulsory published column, apart from the table above "AssignedCriteria".. Even when I attempt to select this column in the article properties page and press ok, when I come back it is deselected again. ( The Rowguid column is however physically added to the table)
I have scripted the publication SQL and then totally reinstalled from scratch, including the database but for some reason it doesn't like this table. I remove the article filters, but still this "rowguid" is never "selected" in article properties.
We are using Uniqueidentifiers in other columns as well for historical reasons, but this doesn't appear to be a problem in other tables..
